Description

Technical Field

[0001] The utility model belongs to the technical field of machining fixtures, and particularly relates to a machining locking fixture. Background Technique

[0002] Machining is a process of changing the shape, size or performance of a workpiece through mechanical equipment. It can be divided into cold working and hot working according to the temperature state of the workpiece during processing. Cold working is usually carried out at room temperature and will not cause chemical or phase changes in the workpiece, while hot working is carried out at a temperature higher or lower than room temperature and may cause chemical or phase changes in the workpiece. Cold working and hot working are further subdivided into cutting machining and pressure machining.

[0003] When the existing equipment is in use, due to insufficient clamping force, the object will not be tightly clamped and will fall off during the clamping process. At the same time, due to improper rotation inside the equipment, the equipment will operate unsafely, thus hurting the staff. At the same time, the pressure generated on the clamped object during the clamping process is too large, which is likely to cause damage to the clamped object. Therefore, we propose a machining locking fixture. Summary of the Invention

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a rotating mechanism. When the staff uses the device, the manual rod is supported by the support plate, and the pinion and the large gear of the manual rod rotate relative to each other through the rotation of the manual rod, which can change the rotation direction of the rotating rod, achieving the effect of changing the movement direction. When the rotating rod rotates, it drives the moving plate to move through the threaded connection with the moving plate. When the moving plate moves, it drives the moving block at the top to move. The moving block slides on the surface of the sliding plate, improving safety and achieving the effect of placing an object. Place the object to be clamped on the placing plate. The roller frame rotates by being pushed through the threaded connection with the rotating rod, playing a connecting role. When the roller frame rotates, it drives the roller frame to rotate through the sliding connection with the roller frame, making the rotation of the rotating rod smoother, achieving the effect of pushing the machine and preventing the machine from operating unsafely.

[0015] 2. The utility model is provided with a shock-absorbing mechanism. The second fixed rod is more stable through the support of the fixed plate. The second fixed rod fixes the fixed block through the connection with the fixed bottom plate, making the fixed block have a fixing effect. A spring chamber is fixedly connected to the outer wall of the spring fixing plate, and a shock-absorbing block is fixedly connected to the outer wall of the spring chamber. A second spring is fixedly connected to the outer wall of the shock-absorbing block, and a clamping plate is fixedly connected to the outer wall of the second spring. When using the device, when the clamping plate moves, it drives the clamping plate to clamp the workpiece through the connection between the second spring and the spring. When the clamping plate continues to move towards the surface of the workpiece, the clamping plate will be forced to squeeze the second spring to contract, reducing the impact force of the clamping plate. By squeezing the spring, it has a buffering effect, achieving the effect of making the clamped object more stable, and at the same time having a decompression effect to prevent the object from falling.

[0016] Of course, it is not necessary for any product implementing the present utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
